Auto switch: When and how to use it

Every ERA plug-in has an OUTPUT slider which you can use to adjust the output level. That way you can compensate any level difference between the original audio and the repaired one. 

For example, when using a dereverberation plug-in, like ERA Reverb Remover, due to the nature of dereverberation, the level of the output signal will be significantly lower compared to the original. This is expected, because when we remove the reverb from a recording,  although we improve the SRR (Signal-to-Reverberation ratio), we also decrease the Dynamic Range* of the original signal.

The OUTPUT gain works as a make-up gain and allows you to adjust the level of the output signal. In addition to this, ERA Reverb Remover features an AUTO option as well, which automatically optimizes the output level based on continuous calculations under the hood.

Note: When AUTO is enabled, it only applies to the output level of the processed signal. It’s not related with the dereverberation process.

* Dynamic Range is the difference between the quietest and loudest signal of a recording
